That’s how one girl, involved in building a model of the Margaret Hunt Hill Bridge, describes this latest piece of striking Dallas architecture in a new documentary sponsored by the Trinity Trust, a foundation created to help the city find private funding for the Trinity River Corridor Project.

The project includes the Santiago Calatrava-designed structure connecting downtown and West Dallas.

Over the course of Calatrava Student Constructors, a 20-minute educational film premiering Monday at the Texas Theatre in Oak Cliff, the descriptions become more specific as the students learn from its builders how the vehicular bridge was engineered. The film follows their one-day journey last May from the site to the classroom to the Trinity Trust offices, where they made the 20-foot-long replica.

What we learn: White steel pieces for the dramatic 40-story arch came from Italy, where they were put together for a test and then taken apart for shipping. Concrete used for the deck, which will accommodate six lanes of traffic, had to be poured from both sides simultaneously to ensure an even surface. Fifty-eight cables hold the bridge up.

“You really get an understanding of how the bridge fits together,” says Simon Cohen, among a dozen eighth- and ninth-graders from public and private schools who were selected by youth-program officials at Southern Methodist University to participate in the model project. Cohen, a freshman at the Booker T. Washington arts magnet, went on to speak about his experiences at the TEDxKids conference at the Wyly Theatre in December.

Judy Kelly, producer and director of Calatrava Student Constructors, is trying to raise $50,000 to get the film and a teaching guide distributed to local classrooms. Monday’s screenings and a panel discussion featuring engineers, builders and city officials is a beginning.

“If you want people to be interested, you have to educate kids about it,” says Kelly, who previously chronicled I.M Pei’s design and the construction of the Meyerson Symphony Center in the Emmy award-winning Frozen Music. She also is working on a larger documentary about the making of the Margaret Hunt Hill Bridge.

Monday’s program starts with a reception at 6 p.m. and continues with screenings at 6:30 and 8 p.m. The panel discussion will take place at 7 and will include two of the documentary’s stars, civil operations manager Jim McTaggart of the company VSL and Trinity River Corridor Project managing director Rebecca Rasor.
